OSX: Fix linking with osxcross for arm64

For some reason the `-target` option on the `LINKFLAGS` was causing a weird
issue where osxcross' clang wrapper would attempt using the system `/bin/ld`
instead of the osxcross version (which is Apple's `ld64`).

The error message would be:
```
/bin/ld: unrecognized option '-dynamic'
```

Also removed from `CCFLAGS` for consistency, it seems to work fine with only
`-mmacosx-version-min`.
